In loggers we have File appender and Console Appender. These appenders depends on log4j.properties configuration file
# Set the root logger level to DEBUG and its only appender to rolling
log4j.rootLogger=DEBUG, rolling
# Configure the rolling appender to be a FileAppender
log4j.appender.rolling=org.apache.log4j.FileAppender
log4j.appender.rolling.File=./logs/mylogs.log
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.rolling.layout.ConversionPattern=%d [%t] %-5p %c- %m%n
